Humidity Fan App - option for backup sensor

How big of a deal would it be to add an option for a backup sensor? I have a ZSE44 and a ZSE40 in each bathroom. I use the ZSE44 since the ZSE40 will prioritize sending motion events. But it'd be nice to select it as a backup device if the primary device has been inactive for a certain amount of time. Even more awesome if it could flip a switch or send a notification when it decides to do this.
